超高层钢框架-核心筒结构弹性与弹塑性时程分析结果对比研究
|
摘要
利用通用有限元软件ABAQUS建立了超高层钢框架-钢筋混凝土核心筒混合结构的精细有限元模型,对其进行了罕遇地震作用下的弹性时程分析和弹塑性时程分析,充分比较了时程分析获得的计算结果,包括顶点位移时程曲线、基底剪力时程曲线、楼层位移角包络曲线以及地震作用下整体结构的能量反应规律.结果表明:弹塑性分析模型在结构进入弹塑性阶段之后,结构刚度降低,与弹性分析结果相比,结构的地震反应程度更小且存在滞后现象.有关论述和方法可为同类研究提供参考.
The FEM package ABAQUS was adopted to establish the fine FEM mode of super high-rise steel frame-R.C.core wall structure.The elastic and elastic-plastic time history analysis of the structure under rarely met earthquake was carried out in this paper.The calculated results including vertex displacement time-history curves,basal shear time-history curves,floor displacement angle envelope curve,and energy response law of the whole structure were attained.Results show that the structure stiffness will reduce with the structure entering into the elastic-plastic stage.Compared with elastic analysis results,the elastic-plastic analysis will obtain smaller earthquake response.The method mentioned in this paper may be referred for correlative research.
